Аннотация

The detection and evaluation of defects in industrial components relies strongly on ultrasonic inspection techniques. Distance gain size (DG) or reference reflector methods can be improved concerning their localization, signal-to-noise ratio and sizing accuracy by the synthetic aperture focusing technique (SAFT). To obtain a high quality image, parameters like focal probe versus contact technique probe, achieved resolution or features of SAFT images compared with B-scan images are discussed. The implementation of SAFT in a CAD environment allows us to present stacked 2D reconstructions dynamically. On a cladded testblock with half-penny shaped cracks the advantage of combining CAD with SAFT is shown. A 3D SAFT example finalizes the overview of two decades of experience in applying this technique.
